Hi guys,
I am new to oracle database and i was trying to establish connection with oracle database using c++ . Although i have code for connection with db but when I try to compile it using g++ it gives me following error-
In file included from <built-in>:7:
oracle/core/lmx/CoreException.java:44: internal compiler error: in uses_jv_markobj_p, at java/boehm.c:252
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugzilla.redhat.com/bugzilla> for instructions.

The command which am i using to compile cpp file is-
g++ -L $ORACLE_HOME/lib/* -L /root/Shared/instantclient_11_2_4/* -L $ORACLE_HOME/rdbms/lib/* cpp_db_conn.cpp
Here is my cpp file-

#include <iostream>
#include <occi.h>

using namespace oracle::occi;
using namespace std;

int main(){

oracle::occi::Environment* environment;
oracle::occi::Connection* con;
oracle::occi::Statement* stmt;
oracle::occi::ResultSet* res;


environment = Environment::createEnvironment(Environment::DEFAULT);
con = environment->createConnection("tkmah7u", "root", "XE");

stmt = con->createStatement("select * from customers");
res = stmt->executeQuery();

while (res->next())
std::cout<<res->getInt(1)<<" "<<res->getString(2)<<std::endl;


}catch(oracle::occi::SQLException &e){

return 0;

Need your suggestions, why am i getting this error.
Thank you.
